Fuel stain on wing

Recommended Posts

While refueling the CTSW cross-country, I spilled some 100LL on the top of the wing, and didn't have access to water to clean it. Now I have a light brown stain aft of the right fuel filler.

Best way to remove this? Is the surface in danger of delamination, or is it just cosmetic?

Thanks!

My fuel collar has a very slow leak during flight that puts a streak on the wing. I finally settled on alcohol as the best, it removes it instantly. Of course it removes everything else too, so I have to renew the Composiclean wax right away. Alcohol also works well for all but the most stubborn streaks on the belly as well.

What's funny, is that one of the best solvents for gasoline stains... is gasoline.

So true.

It almost instantaneously breaks down the fuel stain, so it can be absorbed by a paper towel. I follow it up with a water moistened paper towel, then hit the spot with spray Composiclean or Turtle Ice.

Turtle Ice is great stuff. Good for the windscreen also.
